This is working for the selection of a single Node/Sensor. However, the flow joins the DB output when multiple items are selected, thus creating an array of data. I've found a similar post here Dynamic series identification from message, send data to Chart - #5 by Steve-Mcl; however, the output is different.
My apologies for creating more work. Your help is greatly appreciated.
